1 Scope
This standard specifies the terms and definitions, classification, grades, specifications and labeling, raw materials, requirements, test methods, inspection rules, marking and certificate, transportation, packaging and storage of non-asbestos fiber cement flat sheets (hereinafter referred to as non-asbestos sheets).
This part is applicable to the non-asbestos sheets used as interior wall panels, exterior wall panels and suspended ceiling boards in buildings, clapboards in carriages, offshore buildings and vessels as well as composite insulation panels with fire-proof, heat insulation and moisture-proof requirements, and is also applicable to those used for other purposes such as home decoration.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
fiber cement flat sheets
sheets manufactured through forming, pressurizing (or non-pressurizing) or high pressure steam (or non-high pressure steam) conservation with cement as cementitious material while organic synthetic fiber, inorganic mineral fiber or cellulose fiber as reinforcing material
3.2
non-asbestos cement flat sheets
fiber cement flat sheets made with non-asbestos fiber as reinforcing material
3.3
sanding
the surface flattening process of sheets after conservation and hardening
3.4
the high pressure steam conservation
the process of placing the prepared blank into an autoclave for saturated steam conservation at about 0.8MPa~1.0MPa and 180℃ to stimulate the activity of siliceous and calcareous materials in the raw materials, promote hydration reaction and generate strength during sheet production
